NUT 3/8 UNF - Replaces (NM21998, 060029, 063245, 46-0006)
A 3/8 UNF nut used across multiple frame, engine, and suspension fittings.
This is a 3/8 UNF nut, one of the general-purpose fasteners that shows up all over the catalog wherever a 3/8 UNF stud or bolt needs securing. Our records show it turning up in figures covering the frame, the swinging fork and suspension units, engine fittings and exhaust, the crankcase, and even the front wheel on the T100R, which tells you this is a common hardware item rather than something tied to one specific assembly.

Because it's used in so many places, exact placement on any given bike comes down to which stud or bolt you're working with. The catalog carries a handful of older reference numbers this nut has replaced over the years, so if your parts book lists NM21998, 060029, 063245, or 46-0006, this is the current number for that same nut.
It's a plain, straightforward piece of hardware, worth having a few on hand since it fits so many spots on the bike. If you're not sure which stud it's meant for on your machine, bring in the old nut or give us a call and we'll match it up.
